Generate Form Mappings for Same Server Type Migrations

Scope: Service Now -> Service Now Migrations and Remedy -> Remedy Migrations

This document describes functionality available in the 8.1 release or later.

For Service Now Instance migration and Remedy Server replatforming Migrations where little manipulation of the data is required, the form mappings required can be quickly generated using the Project->Generate ->Generate Form Mappings menu option. This will display the following dialog:

This function allows you to select a set of source tables and generate 'default' form mappings for them.

The opening page gives an overview of each step in using the wizard.

It may be required to edit some areas of the mappings to fit your exact migration requirement. OTB, the mappings generated can:

• Have a source filter restricting the records migrated to those of the table's class. This filter is only added If the table is extended by any other one.
• Migrate the sys_id for the source record to the target. This will mean that an existing target record with the same ID as the source record will be updated, otherwise a new record will be created.
• For Service Now instance migrations ONLY, if reference tables are selected in the wizard, reference fields will use reference mappings to ensure data integrity. See more information here
• If configured using the Is Delta Migration option, add a source filter to migrate only records updated since the last time the project was run, using the LAST_EXECUTION_TIMESTAMP variable.
• If configured, include attachments in the migration.
• If a Parent/Child relationship is configured, add an inclusion filter to ensure only child records for migrated parent records are included. 
• Use simple mappings for all other target fields, where the source field of the same name is used to populate the target field.
